Gertsch & Soleglad, 1972:
holotype from Mission San Borjas, 1500 ft., Baja California Norte, México,
June 20, 1968 (S. C. Williams, M. A. Cazier, etc.) in collection of
California Academy of Sciences.
Gertsch & Soleglad,
smooth, brownish scorpion similar to huachuca, distinguished by
following features: total length of male 26.3 mm., of larger female 31.6
mm.; median ocular tubercle situated well in front of middle of
carapace; pectinal tooth count of females 12, of males 13; chela stout,
with short fingers, and keels weak and mostly smooth; lower margin of
movable finger ofchelicera crenulate, with about five weakly rounded
lobes; all of chelicera crenulate, with about five weakly rounded lobes;
all keels on cauda crenulated or granulated; vesicle lightly inflated in
front of sting.
COLORATION: Base color ofadults light yellowish brown, of immature
specimens much paler. Carapace dusky in front half with faint mottled
darker pattern; eye tubercles black. Cauda somewhat darker brown, with
keels reddish or black. Chela also darker, with dark reddish fingers and
reddish keels. Sternites of preabdomen pale yellow; pectines whitish.
Vesicle of sting yellow; sting dark red.
STRUCTURE: Similar in both sexes to those of huachuca in all basic
features, unless otherwise indicated. For measurements, see table 6.
Carapace: See figure 131. Carapace quite smooth over most of surface,
shiny, with few, weak, inconspicuous granules in posterior median groove
and along sides behind ocular triangle; frontal lobes with six reddish
bristles, irregularly spaced in holotype. Frontal emargination widely
rounded indentation. Ocular tubercle situated back one-third distance
between front and posterior margin. Median ocular tubercle small,
smooth; median eyes small, 0.2 mm., separated by diameter. Lateral eyes,
three; third eye smallest.
Preabdomen: All tergites quite smooth, shiny, posterior ones with weak
granulation, especially along hind margins. Tergite VII with dorsal and
lateral keels fairly well developed, each provided with about 10 rounded
granules giving crenate appearance in side view; intercarinal spaces
with few weak granules.
Telson: See figure 132. Vesicle oval, broader than fifth caudal segment,
flattened and smooth above, lightly inflated behind in front of sting,
with smooth granulation on sides and below, provided with few short
hairs. Sting about half as long as vesicle.
Pectines: Of female, median piece twice as broad as long, with wide,
shallowly V-shaped emargination on front margin; pectin more than twice
as long as median piece (58/23); middle lamellae, eight or nine;
pectinal count, 11. Of males, shorter, emarginated median piece and much
longer pectin (52/21); middle lamellae, seven or eight; pectinal teeth,
Chelicerae: See figures 30, 31. With basic pattern of mordax group; keel
on lower margin of movable finger with irregular crenations, without
distinctive dark teeth; keel on fixed finger with three pale teeth near
Pedipalps: Keels on femur prominent, armed with rounded granules to give
mostly crenulate appearance in lateral view; those on tibia less
developed, quite smooth, crenulated; frontal spurs on tibia rounded,
with single granule set with long reddish seta. Chela very stout, with
movable finger shorter than palm, quite smooth, with most carinae weak
and smooth; inner side of palm and area below set with weak, rounded
granules; superior carina weakly developed, smooth except for alveolae
of weak setae. Keels on fixed and movable fingers with single line of
minute denticles, broken into six files by six larger teeth, and flanked
by six heavier, triangular teeth.
Walking legs: Legs with sparse covering of reddish bristles and weak
spines, with basic features of those of huachuca. Venter of tarsus with
two or three fine spines on each side of median line of spinules.."
Diagnosis. - Adults
to 32 mm long. Base color of cuticle uniform golden-brown. Pectine teeth 10-12 in females, 12 in males. Pedipalp with swollen chela; ratio of movable finger length to carapace length about 0.8; ratio of fixed-finger length to palm length about 0.3; ratio of chela length to palm width about 3.0. Chelicera with ventral margin of movable finger with about 5 weakly developed crenulations; 7 supernumerary granules on movable finger, 6 on fixed finger; fixed finger with trichobothria ip
and id midway between finger origin and supernumerary granule 7. Metasoma with ventromedian and ventrolateral keels crenulate; length metasoma segment
III approximating width.

male and female, subadult female and two males, three immatures.
Gertsch and Soleglad (1972) dedicated
this species "to Dr. Mont A. Cazier of Arizona State University, Tempe,
Arizona, who through the years has collected many hundreds of scorpions from
arid regions of the United States and Mexico." Stahnke (1974a: 136)
transferred Uroctonus cazieri Gertsch & Soleglad, 1972 to the genus
Vaejovis; it thus became a secondary junior homonym of Vaejovis
cazieri Williams, 1968. The replacement name, Vaejovis montcazieri,
was proposed by Williams (1980). Since the species is now listed under
Pseudouroctonus, the Gertsch & Soleglad name is no longer a homonym. It
has priority as Pseudouroctonus cazieri and Vaejovis montcazieri
becomes its junior synonym. Williams (1980)
stated, "This species
is distinctive within Vaejovis in having small denticles developed along the ventral margin of the movable finger of the chelicera. This character would associate the species with the genus
Paruroctonus, however, it appears more similar to Vaejovis rufulus,
Vaejovis andreas, Vaejovis lindsayi, and Vaejovis minimus. The small denticles on the chelicerae appear to have developed secondarily and do not appear as evidence of a relationship with
This species was originally named Uroctonus cazieri by Gertsch and Soleglad
(1972). In 1974, Stahnke placed it in the genus Vaejovis. In so doing, a junior homonym was created because the name
Vaejovis cazieri was already occupied by Vaejovis cazieri Williams, a species described
from Coahuila, Mexico (Williams 1968d: 12-15). Williams (1980)
therefore proposed the name Vaejovis montcazieri as a replacement of
the name Vaejovis cazieri (Gertsch and Soleglad), retaining
Vaejovis montcazieri Williams in the minimus group of Vaejovis.
